3M 7100077038 Abrasive Disc 1.5 Inch 40 Grit 30000 Rpm

Product Description

The 3M 7100077038 is a Cubitron II Roloc Durable Edge Disc rated at 40 grit and designed for high-speed grinding and finishing applications up to 30000 RPM. Built on a heavy X-weight poly-cotton backing, this 1.5-inch disc is engineered to withstand edge work without fraying or tattering. The Roloc quick-change attachment system allows fast, tool-free disc changes, keeping downtime minimal on the job. Licensed tradespeople working metal fabrication, weld dressing, and surface prep will find this disc suited to demanding production environments where abrasive life and consistent cut rate matter.

This disc is intended for use with Roloc-compatible right-angle grinders and die grinders in both shop and field settings. The 40-grit designation makes it appropriate for aggressive stock removal and edge blending on metal substrates. Its compact 1.5-inch diameter allows access to tight radii and contoured surfaces where larger discs cannot reach. Typical users include metal fabricators, maintenance welders, automotive body technicians, and industrial grinding specialists.

Key Features

• Cubitron II Precision-Shaped Grain delivers sharp, cool, and consistent cutting action throughout disc life
• Evenly spaced grain layout creates channels that allow swarf and debris to escape, reducing loading
• Heavy X-weight poly-cotton backing resists fraying and tearing during edge work
• Roloc quick-change attachment system enables fast disc-to-tool mounting without additional hardware
• 40 grit rating suited for aggressive stock removal and weld dressing on metal
• 30000 RPM maximum speed rating supports use with standard die grinders and right-angle tools

Compatibility

Designed for use with Roloc-compatible right-angle grinders and die grinders accepting 1.5-inch quick-change abrasive discs.

Installation Notes

Installation and disc changes should be performed with the grinder powered off and unplugged or with its pneumatic supply disconnected. Verify the tool's rated RPM does not exceed the disc's 30000 RPM maximum before mounting. Inspect the disc for damage before each use and discard any disc showing fraying, cracks, or separation. Abrasive disc work on metal typically falls under ANSI B7.1 and applicable workplace safety standards governing grinding operations.
